10.3.2. Valves with Auxiliary Control Air
In the case of valves that are to be employed for a wider range of pressures, the pilot control valve is supplied
with air via a separate pressure port. This should be connected to port X.
10.4. Plug to Block P-channel
Optionally, the pressure supply of the system can be segmented using a partition in the central P-channel
between two pneumatic modules. This allows different pressure levels or different media to be used in the same
system.
With pre-assembled systems, the position for the partition is indicated on the appropriate pneumatic module.
